Final answer:
The given statement 'Enzymes Equation for Catalytic Efficiency: the Cat pounces on top of the Mouse' is false. The efficiency of an enzyme can be described using the ratio k/KM. When all enzyme binding sites have a substrate bound, further increases in substrate concentration do not increase the reaction rate.
Step-by-step explanation:
In an enzyme-catalyzed reaction, the substrate binds to the enzyme to form an enzyme-substrate complex.
If more substrate is present than enzyme, all of the enzyme binding sites will have substrate bound, and further increases in substrate concentration cannot increase the rate.
The efficiency of the enzyme can be described by the ratio k/KM, which allows a relative comparison between enzymes and provides an absolute comparison to the "perfect" enzyme.
